Optima mid custom special
 

Hi Guys

After the ZX-S is complete, I fancy a OMCS. Are there any NIP parts that you simply can't get??
Outside the Lazer range I think this buggy is gorgeous!

Cheers

p.s. thanks for the pinion solution. Vintage pinions and TM-7 Spur ordered for my ZX-R shelfer and MkII runner.

Ill second that, its a stunning looking buggy, don't see many either, but then i dont follow Kyosho too closely.....the brand, at least in vintage terms, makes my wallet ache :p

OT-69 (wishbones)
OT-95 (plate set)
OTW-8 (plastic belt covers)
OT-103 (random plastic thingy)
OT-122 (chassis)
OTW-6 (upper deck)

I'll ignore the usual wheel, tyre & shock issues.

These are the parts that I can't find after a quick look.
Let us know if anyone has this stuff.

Nick :-)

If OT-122 is the fibreglass chassis and NOT the metal chassis, I do have one here I could sell.
Might have an upper deck too actually just need to go through all my stuff
I forget what the OT-103 is, is that the piece that goes over the motor and attaches to the belt cover, if so I reckon I may have one of these too, I need to organise all my parts ....

For belt covers just go with the Marwan repros, the chance of finding the originals is very slim and really not necessary as the LWB belt covers are actually clear anyway unlike the SWB cars which had the tinted belt covers

Cool! Let me know when you've had a mooch. FG chassis is fine, unless Fiberlyte's carbon LWB optima mid will work?

OT-103 is the 'tape set', which effectively is the tape strips that hold the belt guide to the lower chassis plate, the foam/rubber tape that sits either side of the rear wishbone pin holder and the rubber section at the rear of the upper belt.

OTW-1 - the option stabiliser set is also pretty rare these days

Teambluegroove also sell bodies, belt guides and pinion/spur covers in clear lexan.

Fibrelytes chassis will work but if you are trying to build an authentic replica you need either the metal chassis or the fibreglass one.

I have two here, one has some writing on it and a couple stains, that I only want ten pounds for it if you are going to run a painted undertray then it probably will be fine

The other is in great condition, close to mint and I want thirty pounds for that though I may want to keep it as I have a custom special here and I want to check that its not better than the chassis on the built car

I have an upper deck for ten pound but I really only want to sell that with the chassis as a set

These prices are what I paid for the parts, if you think its too much I wont get offended

Dan

Cheers Dan

Sadly without the plate set I'm off on the wrong foot already.
I'm wondering whether the one on eBay AU for £250 might be a better bet

Nick

Probably I can fix a new plate set OT-95 for you.....
I can check if you want?

If you are planning on building one from only NIP parts, quite often a complete kit is cheaper. Add up the prices of all the parts you've already found and take a guess at the others, and don't forget the kit will have original tyres, body and stickers in there as well.

I'm thinking you're probably right.
Asking the Aussie for an offer price atm.

Rear diff
 

Can anyone explain how the rear ball diff works on the optima mid?
I've found the gear and it just occured to me that the gear and belt sprocket are right next to each other.
So how does the thrust balls touch both end friction plates???
Or am I being dumb?

This is what I've found for my OMCS.

Can I make a rear diff with this and a W0107 front ball diff set?

Nick

Yes you are :lol:
The ball diff works like any other, the only difference between the front and rear diffs is that the rear diff has the pulley moulded on the other side of the drive gear, kinda stuck on the side as a ring at the outer edge.

Yes, the only difference between them is the gear/pulley, everything else is identical.

OMCS Build Confirmed!
 

Hi Peeps.

I have taken the plunge and ordered everything I need to make a Custom Special (cos I think it's gorgeous!).
And I bet It'll be finished before the ZX-S! Bloody LAW-12!! :thumbdown:

As soon as I take delivery on parts, I'll take some pics.

Bo!

Surely you can get on with the zx-s now?

My OCD won't let me! Now come on chaps, we restore vintage RC models. Don't pretend nobody else on here is not a little OCD?
Tbh, I can't follow the manual cos LAW-12 is one of the earlier parts required.

What exactly is law -12 again?

The main shaft, the splined pulley drive and the spur slipper plate.

Front diff built out of boredom
 

Front Optima ball diff. W-0107.
Nice.

W-0107

Why is the special special?
What's the difference between it and any other LWB mid?
Nick :eh?:

If you mean the Custom Special, it's just a long wheelbase normal Turbo Mid. The differences between a Custom and Custom Special are the gold shocks, front UJs and turnbuckles.

The Turbo Optima Mid Special is the big one. That came with all options including and was the only kit that came with ball diffs. It also included two sets of Option House tyres on three piece yellow wheels. It was only available in limited numbers, which is why they are hard to find.

That's odd Terry...just took apart my mid SE and that had a ball diff in the front and back!

Yeah, the Mid SE also came with ball diffs. Forgotten about that, as the SE wasn't available in the UK back then so wasn't in my r/c history and I tend to forget about it.

It's ok Terry...even the best of historians have lapses :D

Though, it's the first Kyosho I've seen with my own eyes that has ball diffs.

It's all in bits now getting a good clean.

Ah ok. Well I'm building mine with ball diffs.
I haven't bought shell, wheels or tyres yet so shall I make it a mid special instead?

OT-122 Available
 

Hi peeps

Dunno if you've all seen but Myles from Vintage-kyosho has got 5xNIP Ally Optima Mid LWB chassis.
Always nice for a new build.

Ball Diffs Complete
 

Mmm, nothing nicer than a shiny brand new vintage diff (well apart from all modern ones, lol)

Nick

HI Crash,
I dont know if you got the fiberglass chassis or not, but there is a guy selling one one ebay right this moment!

Also found this LAW 12 for the ZX-S

Pulley

;) Thanks dude. Saw both of those. I've already got the shaft. Just need the inner slipper plate and drive spline.

But the chassis is interesting.
Mid LWB came in Ally, FRP & Carbon. Which went with what?
Atm, I've got a carbon chassis and ball diffs which I assume doesn't really make my build an OMCS does it?

Nick

I think:

SWB

Mid (alloy) OT-91
Turbo Mid & Turbo Mid SE countersunk alloy chassis OTW-3.

LWB

Mid Special chassis (carbon) OTW-5,
Mid Custom (alloy) OT-122
Mid Custom Special (FRP) OT-128

Note: As Terry states on another forum: Mid Custom Special was FRP OT-128, also OT-122 as it was also a production change on the Mid Custom.

But happy to be corrected :)

Sound good to me!
So basically, I'm really making a Turbo Mid Special! Lol
Have you seen the sellers other items above! He's split a custom box! Don't wanna think how much the wheels will fetch :o
N

Yep, it threw me when I got hold of a Mid Custom that should have had an alloy chassis but had the FRP one fitted, and the manual included a piece of paper stapled on the front of it pointing out the chassis change.

Screw set's arrived!! Woop woop! Build shall commence as soon as the wife allows. ;)

Finished! (sort of)
 

Electrics, undertray and gear cover and she's ready to go :)

And I know It's not a OMCS, lol
Carbon chassis, ball-diffs and cheaper orange wheels made a TOMS more logical.
(I like the orange decals with these wheels)
Nick

Its a great result. So what if its not as per the guide book, its got a combination of parts and a great appearance that anyone would be happy with.

I'm almost complete on my own OMCS and that has fibre-lyte parts and a OMC body as I prefer the squarer cockpit.

The beauty of these Kyoshos is the interchangeability of parts, so you can mix and match and still have a great car.
